without giving the optional priority, the default priority will be set. The default priority
decrement is 10. The default priority decrement is changed using the <priority> argument.
no ip vrrp track ip route
Use this command to remove the route from the tracked list or to restore the priority decrement
to its default. When removing a tracked IP route from the tracked list, the priority should be
incremented by the decrement value if the route is not reachable.
ip vrrp accept-mode
This command is used to allow a router to respond to ICMP Echo Requests sent to an address on a
VRRP virtual router. VRRP supports responding to pings, but does not allow the VRRP Master to
accept other types of packets. A new configuration option controls whether the router responds
to Echo Requests sent to a VRRP IP address.
The VRRP Master responds to both fragmented and unfragmented ICMP Echo Request packets.
The VRRP M
aster responds to Echo Requests sent to the virtual router's primary address or any
of its secondary addresses.
Ping to a VRRP IP address only works from the host side (where the VRRP router is configured).
There is no v
alue in pinging to the VRRP IP from another interface because packet flow from the
network to the host does not involve VRRP. This is used only to troubleshoot a connectivity
problem for traffic originating on the VRRP protected LAN.
Members of the virtual router who are in backup state discard ping packets destined to VRRP
addres
s(es), just as they discard any Ethernet frame sent to a VRRP MAC address. When the
VRRP master responds with an Echo Reply, the source IPv4 address is the VRRP address and
source MAC address is the virtual router's MAC address.
There is a separate command, ip icmp echo-reply, that contr
ols whether the router
responds to ICMP Echo Requests. When Echo Replies are disabled using that command, the VRRP
master does not respond to Echo Requests, even if this new option is enabled.
